Halfway Between 15 and 458

When you ask "What number is halfway between 15 and 458?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=15 and Y=458.

Halfway Between Line

To find the number halfway between 15 and 458, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 458 into our formula, we get:

(15 + 458)/2 = 236.5

Thus, the number halfway between 15 and 458 is 236.5.

To check that our answer is correct, we subtract 15 from 236.5 and subtract 236.5 from 458 and compare the two numbers:

236.5 - 15 = 221.5
458 - 236.5 = 221.5

As you can see, the halfway number is 221.5 higher than 15 and 221.5 lower than 458. Therefore, our halfway between answer of 236.5 above is correct.
